The measure of supplementary angles adds up to 180°. To find the measure of the supplementary angle to LB, which is 68°, you subtract LB from 180°:
\[
180° - 68° = 112°
\]
So, the measure of the supplementary angle is 112°.
The answer is **C: 112°**.
\[
180° - 68° = 112°
\]
So, the measure of the supplementary angle is 112°.
The answer is **C: 112°**.
